#190172 - PS2 Keyboards are not working Responding to: ???'s previous message |
Hey Andy,
My new and old Keyboards are working fine with ARM and AVR microcontrollers. But new PS2 keyboards are not working with 8051 but Old keyboard works. Is there be any issue with pull up lines. I have attached a RES8-PACK(9 pin 10K pullup sip). I had checked the timing waves on Oscilloscope and it seems ok. Thanks & Regards, |
